The 18-mile Clarion-Little Toby Trail parallels the banks of the Clarion River and Little Toby Creek in Elk County, Pennsylvania, in the heart of the region known as the Pennsylvania Wilds. The trail utilizes the right-of-way of the former Ridgway and Clarion Branch of the Pennsylvania Railroad between Ridgway and Brockway.

During 2015, Rails-to-Trails Conservancy (RTC) conducted this study of the users of the Clarion-Little Toby Trail under a grant from the Pennsylvania Department of Conservation and Natural Resources. The survey was designed to monitor trail user characteristics and economic impact.

An analysis of the data accumulated from infrared counters located along the trail and the completed surveys received from users indicate an estimated 20,761 annual user visits, resulting in a total economic impact in 2015 of $897,593.
